Why User Experience (UX) is the Secret to App Success

With so many competing apps today, user experience (UX) design is now the pivotal factor determining an app's chances of success. Simply incorporating features into an app isn't the answer; it's about the overall experience and how users feel about using the app. As Softura points out, “The success of any app isn’t just about its features; it’s about how users feel when they interact with it”. In summary, a seamless and intuitive user experience (UX) can convert infrequent users into loyal ones. In other words, great UI/UX design makes it feel effortless to use the app (“wow, that just works”), which will result in the user returning time and time.

What is UX (and UI) in App Design?

UX design is concerned with all aspects of a user’s encounter with an app, from the onboarding flow to navigation and visual layout. (UI design refers more specifically to the look of the app - colors, fonts, buttons, and layout; while UX design refers to everything - is it intuitive and efficient?) A great user interface (UI) can catch users’ attention in a matter of seconds, while a poor user interface will cause users to leave. In fact, users can determine in just the first few seconds of downloading an app whether or not to stay and use it. As Softura explains, “An attractive, intuitive design will make users stay, while navigation that is clunky will make users run." Therefore, good UX design is the basis of a positive first impression that will help drive future engagement and retention from the start.

UX Drives Retention, Engagement, and Loyalty

Put simply, users stay when they are happy. Apps designed with great UX remove frustrating “roadblocks” (for example, unclear menus or sluggish performance), so users enjoy the experience and return often. On the contrary, poor UX contributes to the rapid removal of your app and negative reviews. It has been shown in research that if users have difficulty or become frustrated, they will “ditch your app faster than you can say ‘uninstall’”. High retention is literally “the secret to app success,” according to Sunvera Software, and apps must get users coming back again and again. Repeat users correspond directly to revenue, and satisfied users will not only stick around, but they will also advocate for the app by recommending it to their friends. One study found that 90% of smartphone users are more likely to continue to shop or use an app if the experience is great, and 74% of users will return to a site with good mobile UX.

• High Retention & Loyalty: When you invest in UX, you are essentially buying brand loyalty from your customers. A seamless user experience will lead to customer satisfaction, and satisfaction is directly correlated to building long-term customer loyalty.
• Positive Reviews & Word-of-Mouth: When users are happy with their experience, they are more likely to provide high star ratings and actively recommend it to others. Glance sums it up nicely: “happy users turn into positive reviews, more downloads, and ultimately better sales.”
• Reduced Churn: When you eliminate friction points (e.g. poor navigation), your app will see a reduced (and expensive) churn rate. For example, apps that minimize clicks required to complete an action generally report greater satisfaction and retention rates.
• Cost Savings: Good UX means saving money on customer service and support. Good UX translates into fewer user help tickets, complaints, and fewer nagging support issues, resulting in less time and less outlay of development resources.

Overall, there seems to be a clear correlation between UX and customer loyalty. As we’ve mentioned, “happy users bring positive word of mouth, positive app ratings, and ultimately more downloads and revenue.” This cycle of good UX leading to engaged and lucrative users means that you can never stop striving to have better UX for your app or game.

Business Impact: Conversions, Revenue, and Growth

Excellent UX provides more than just smiles; it drives business results. Numerous studies are showing that a UX investment can result in significant improvements in key metrics. For example, Walmart analyzed its sites and said it sees a 2% lift in conversions for every second saved in load times. Similarly, it is said that "a well-done UX design can triple conversion rates" for websites. When it comes to mobile apps, a positive UX impacts a user's install-to-active user rate and spending within the app. In fact, industry reports say that almost half of all apps in the app store are uninstalled within a month of download, which is an easily avoidable fate of bad UX.

In an even more general sense, iLink states that quality UI/UX design is a "powerful growth driver." A high-quality app that balances end-user experience with business goals will "turn them into loyal customers," with positive reviews and higher app-store ratings that lead to higher search visibility. A great end-user experience will positively influence brand image and trust. On the contrary, however, bad UX can negatively affect a brand; one article said that, "nearly 48% of customers feel that a poor mobile accessibility indicates that the business does not care." From a developer perspective, spending early on UX avoids costly rework at the end. Ultimately, fixing usability issues during design is far less costly than fixing problems post-launch. In conclusion, every dollar spent on UX pays back many times over in user adoption and revenue.

Key Elements of Great UX

What makes an app’s UX stand out? Experts highlight several best practices. Key ingredients include:

• User-Focused Design: Develop the app based on authentic user research and workflows. Investigate users' needs and pain points, then develop features that specifically address them.
• Simplicity & Clarity: Keep the screens clean and tasks simple. Do not present users with too many buttons or options, or you will make them feel overwhelmed. Every component (button, icon, menu, etc.) should have a purpose so that users can accomplish their goals with little effort and stress.
• Consistency: Utilize a unified color scheme, typography, and layout throughout the app. A consistent UI creates trust and familiarity with users so that the experience feels like "seeing a friend you can always count on."
• Performance: Ensure upscale speed and performance. Load times that take too long or interactions that bug out can frustrate users immediately. Make sure screens load quickly, animations are fluid, and the app can withstand poor network signals and still work quickly.
• Accessibility: Support design that is inclusive. Features such as adjustable font sizes, high-contrast mode, and voice control not only help you reach broader audiences and demonstrate care, but accessible apps are more competitive and favored by users.
• Personalization: Personalize the experience when it is possible. More recent research has confirmed that personalization significantly increases conversions. For instance, by personalizing content or recommendations to each user, the app should feel like an essential tool to each user.

When developers implement these user experience (UX) best practices, essentially user-first, they are creating apps that users will love. As one other expert said, “a well-considered, user-centered design is the lifeboat” in this vast, digital ocean.

Conclusion

In short, the “secret sauce” to success in app building is very simple: prioritize user experience from day one. All the data and expert insights point to apps with stellar UX as being the ones that outperform their competition. They keep people engaged (greater retention), they create buzz (better reviews and more word of mouth), and they drive important business goals (increased conversions and revenue). Every design decision, the flow of the navigation, and the color of the buttons should be made to a user experience that is easier and more enjoyable. Apps with user experience that are effective not only survive, but they also gain momentum.
